Essential oil of the herb of Stachys recta L., Lamiaceae from Serbia

Abstract

The aerial parts of wild Stachys recta L., Lamiaceae, collected in the vicinity of Nis (Southern Serbia) during the full blooming stage, contained only 0.014% of essential oil. Using GC and GC/MS, 32 components were identified, predominantly alcohols and adequate oxides. The major constituent was 1-octen-3-ol (19.7%). The other important components were caryophyllene oxide, humulene oxide and nerolidol, but present in significantly lower amounts (4.6%, 3.8% and 3.6%, respectively).
